The Weekly Leading Index (WLI) of the Economic Cycle Research Institute (ECRI) rose for the fourth consecutive week, now at 123.6 from last week's 123.3. See the WLI chart below. The WLI growth indicator (WLIg) has risen into expansion territory at 0.6 after nine consecutive weeks of improvement.

As of today, the ECRI website still features Lakshman Achuthan's July 10th Bloomberg TV interview, in which he reaffirmed his company's recession call and stated that we're already in a recession (link to video).

A cornerstone of his argument is that four key indicators used by the NBER to make official recession calls are, as he put it, "rolling over." Here are the four indicators in question. Only one, real retail sales (which is the most volatile of the lot) had been showing intermittent signs contraction but subsequently improved in the July data. There is no question that the recovery from the Great Recession has been frustratingly slow, but the overall trend has been one of improvement. The next of the Big Four, and the first for August data, will be next Friday's employment report.

Of course, the recent months for these data series are subject to revision. But at this point, economic data have consistently contradicted Achuthan's "rolling over" assertion and claim that we're now in a recession, a position that is rapidly becoming an embarrassment.

For more background on these four economic indicators, see the following articles:

For a better understanding of the relationship of the WLI level to recessions, the next chart shows the data series in terms of the percent of the previous peak. In other words, a new weekly high registers at 100%, with subsequent declines plotted accordingly.

As the chart above illustrates, only once has a recession occurred without the index level achieving a new high -- the two recessions, commonly referred to as a "double-dip," in the early 1980s. Our current level is 14.1% off the most recent high, which was set over five years ago in June 2007. We're now tied with the previously longest stretch between highs, which was from February 1973 to April 1978. But the index level rose steadily from the trough at the end of the 1973-1975 recession to reach its new high in 1978. The pattern in ECRI's indictor is quite different, and this has no doubt been a key factor in their business cycle analysis.

The WLIg Metric

The best known of ECRI's indexes is their growth calculation on the WLI. For a close look at this index in recent months, here's a snapshot of the data since 2000. It is the recent behavior of this indicator that most clearly suggests that ECRI has painted itself into a corner with its unequivocal recession call.

Now let's step back and examine the complete series available to the public, which dates from 1967. ECRI's WLIg metric has had a respectable record for forecasting recessions and rebounds therefrom. The next chart shows the correlation between the WLI, GDP and recessions.

ECRI's weekly leading index has become a major focus and source of controversy ever since September 30th of last year, when ECRI publicly announced that the U.S. is tipping into a recession, a call the Institute had announced to its private clients on September 21st. Here is an excerpt from the announcement:

Early last week, ECRI notified clients that the U.S. economy is indeed tipping into a new recession. And there's nothing that policy makers can do to head it off.

ECRI's recession call isn't based on just one or two leading indexes, but on dozens of specialized leading indexes, including the U.S. Long Leading Index, which was the first to turn down — before the Arab Spring and Japanese earthquake — to be followed by downturns in the Weekly Leading Index and other shorter-leading indexes. In fact, the most reliable forward-looking indicators are now collectively behaving as they did on the cusp of full-blown recessions, not "soft landings." (Read the report here.)

Year-over-Year Growth in the WLI

Triggered by another ECRI commentary, Why Our Recession Call Stands, I now include a snapshot of the year-over-year growth of the WLI rather than ECRI's previously favored method of calculating the WLIg series from the underlying WLI (see the endnote below). Specifically the chart immediately below is the year-over-year change in the 4-week moving average of the WLI. The red dots highlight the YoY value for the month when recessions began.

As the chart above makes clear, the WLI YoY is currently at a lower level than at the starting month for five of the seven recessions during the published series. The latest weekly reading, -1.4% (-1.44 to two decimals), is up from last week's -2.89%. The behavior of this indicator over the next quarter or so will be especially interesting to watch.

Additional Sources for Recession Forecasts

Dwaine van Vuuren, CEO of RecessionAlert.com, and his collaborators, including Georg Vrba and Franz Lischka, have developed a powerful recession forecasting methodology that shows promise of making forecasts with fewer false positives, which I take to include excessively long lead times, such as ECRI's September 2011 recession call (barring a future NBER announcement of a Q1 2012 recession start).
